UNITED STATES PATENT OFFIoF FRANK A. REIHER, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF HIS nrenr'ro o. F. BOLLMANN, 0F SAME PLACE.

IMPROVEMENT l'N TRANSOM-LIFTERS.

Specification forming part of Letters Patent No. 186,166, dated January 9, 1877 application filed August 16, 1876.

To all. whom it may concern:

Be it known that I, FRANK A. REIH R, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Transom-Lifters,which improvement is fully set forth in the following specification, reference being had to the accompa nying drawings:

The object of my invention is to adjust, lift, or shut transoms or skylights from a distance below; and mainly cdnsists in the arrangement of certain armsv guiding the free (not hinged) end of the transom-sash by means of a gear-segment and a rack-rod, operated upon by'a lever, as will hereafter more fully be described.

In the drawings, Figure l showsa front elevation of my device, the transom being in a partly. elevated position. Fig. 2 shows a side elevation of the same. Fig. 3 shows the lifting-lever with end of rod enlarged. Fig.

. 4 shows a modification in the arrangement of parts, the transom-sash being hinged in a different manner.

The transom-sash A, hinged to the doorframe D in the usual manner, is provided with two guide-rails, a a. Permanently affixed to a rod or shaft, B, turning in two bearings, 12 b, are the arms 0 0, arranged at each end of the transom-sash and tent at their ends, forming finger-like projections d (1, as shown in Fig. 1. The position of these arms 0' G will naturally determine the respective position of Firmly affixed to one end of the shaft B is the gear-segment E, in gear with the rack-rod F situated vertically on the side of the door-frame. The lower end of this is flattened out, as shown in Fig. 3, forming a plate, which is provided with a horizontal slot, f. A casing, H, screwed to the post of the doorframe D, forms a guide for the lower end of rack-rod F. The double-armed lever Gr is fulcrumed at the pin it, fastened to the casing, and operates the rack-rod. Its short arm, with pin g, engages in the slot f, while the long arm is provided with a handle or knob, k, for the operator. The set-screw J on top of the casing serves to hold the rack-rod at any desired position. Respective recesses may be formed in the rack-rod.

The operation is simply as follows: Any movement imparted to the lever G will neces sarily be followed by the pin g, rack-rod F, gear-segment H, shaft B, arms 0' O, and the transom-sash A.

Light transoms may be operated by only one arm, 0, which may be connected directly to the segment, as shown in Fig. 4. Only one rail, a, is necessary, and the shaft B will be reduced to a stationary stud, on which the segment turns.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The arms or arm 0 C, with rails a a, fastened to the transom-sash, in combination with the gear-segment and rack-rod.

2. The double-armed lever G, in connection with the rack-rod F with slot f.
